Re: [IPsec] I-D Action:draft-ietf-ipsecme-traffic-visibility-07.txt

Hi Jack,

I believe it is essential that both this draft and the ESP-null Heuristics
draft contain language that clarifies how they relate to one another. I
posted some text to the list on Aug. 11, and I am still awaiting approval
from the Heuristics group of authors. When we have this point resolved, the
draft is ready to move forward.

Thanks,

            Yaron

I believe this draft had cleared the WG LC long time back. What else are the
chairs/authors waiting for?

       Title           : Wrapped ESP for Traffic Visibility
       Author(s)       : K. Grewal, et al.
       Filename        : draft-ietf-ipsecme-traffic-visibility-07.txt

This document describes the Wrapped Encapsulating Security
Payload (WESP) protocol, which builds on top of Encapsulating
Security Payload (ESP) [RFC4303] and is designed to allow
intermediate devices to ascertain if ESP-NULL [RFC2410] is being
employed and hence inspect the IPsec packets for network
monitoring and access control functions.  Currently in the IPsec
standard, there is no way to differentiate between ESP
encryption and ESP NULL encryption by simply examining a packet.
This poses certain challenges to the intermediate devices that
need to deep inspect the packet before making a decision on what
should be done with that packet (Inspect and/or Allow/Drop). The
mechanism described in this document can be used to easily
disambiguate ESP-NULL from ESP encrypted packets, without
compromising on the security provided by ESP.
